There are several ways of doing it though, as always. You could just use a different template where the address is lower anyway, or you could globally pad the address box down, or remove/move the header and place it somewhere else.

Hmm, just checked mine and and it wraps automatically, PURCHASE ORDER is on 2 lines. The CSS for mine is <div id="PurchaseView1_dvHeader" class="invoice-header">PURCHASE<br>ORDER</div>
